Process for producing optically active compound

ABSTRACT

A highly efficient process is provided for producing an optically active compound having high optical purity by an asymmetric reaction using as a catalyst a transition metal complex having an optically active nitrogen-containing compound as an asymmetric ligand.

BACKGROUND OF THE INVENTION

[0001] 1. Technical Field to Which the Invention Pertains

[0002] The present invention relates to an efficient process for producing an optically active compound having high optical purity by using, as a catalyst in an asymmetric Michael reaction, a transition metal complex having an optically active nitrogen-containing compound as an asymmetric ligand.

[0003] 2. Prior Art

[0004] Optically active compounds obtained by an asymmetric Michael reaction are useful as synthetic intermediates for pharmaceuticals, etc. For example, an optically active ketone obtained by an asymmetric Michael reaction of an enone can be used as a synthetic intermediate for a prostaglandin, etc. With regard to a process for synthesizing these optically active ketones, various processes have been developed, and known examples of asymmetric Michael reactions using an asymmetric catalyst are as follows. For example, there are asymmetric lanthanoid complex catalysts (ref. JP, A, 7-265709, JP, A, 8-291178, JP, A, 11-240865, JP, A, 2001-31682, or JP, A, 2002-69076), and asymmetric aluminum complex catalysts (ref. JP, A, 2001-31682 or JP, A, 8-319258). Furthermore, asymmetric rhodium complexes (ref. JP, A, 10-130286) and asymmetric hafnium, titanium, zirconium complex catalysts (ref. JP, A, 2001-252567) have been reported.

[0005] The asymmetric lanthanoid catalysts, which have a lanthanoid as a center metal, have a different metal such as lithium in the catalyst molecule, and it is thought that the lanthanoid and lithium activate a Michael donor and a Michael acceptor respectively. It is therefore necessary to have two different types of metal in the molecule, and it is thus necessary to design an asymmetric metal complex having a complicated structure.

[0006] These processes cannot therefore be always said to be highly practical since it might be difficult to prepare the catalyst, the catalyst might have a stability problem, it might be necessary to use a large amount of catalyst, or it might be necessary to carry out the reaction at low temperature or for a long time.

[0007] The present invention has been achieved under the above-mentioned circumstances, and it is an object thereof to provide an efficient process for producing a Michael addition product having high optical purity by an asymmetric Michael reaction using a catalytic amount of an asymmetric source under mild conditions.

SUMMARY OF THE INVENTION

[0008] As a result of an intensive investigation by the present inventors, it has been found that a Michael addition product having high optical purity can be obtained highly efficiently by using, in an asymmetric Michael reaction, an asymmetric metal complex that is obtained by reacting an optically active nitrogen-containing compound, a complex of a metal of group VIII of the periodic table, and a base, and the present invention, which is a novel, very efficient catalytic system, has thus been accomplished.

[0433] In an embodiment of the present invention, the optically active nitrogen-containing compound, the compound of a metal of group VIII of the periodic table, the base, and the compounds represented by general formulae (A) and (B) may be reacted by mixing. More preferably, the asymmetric metal complex is prepared beforehand from the optically active nitrogen-containing compound, the compound of a metal of group VIII of the periodic table, and the base, and the compounds represented by general formulae (A) and (B) are reacted by mixing in the presence of this asymmetric metal complex. By carrying out the preparation of the asymmetric metal complex in the presence of a hydrogen-donating compound an asymmetric metal hydrido complex is obtained, and by carrying it out in the absence of a hydrogen-donating compound an asymmetric metal amido complex is obtained. In the preparation of the asymmetric metal complex, the molar mixing ratio of the compound of a metal of group VIII of the periodic table and the optically active nitrogen-containing compound is 1.0:0.1 to 1.0:10.0, and it is preferable to mix molar equivalents of the metal and the optically active nitrogen-containing compound. The base is used at 0.1 to 100 molar equivalents relative to the compound of a metal of group VIII of the periodic table, and preferably 1.0 to 10 molar equivalents. As a catalyst for the asymmetric reaction, either the asymmetric metal amido complex or the asymmetric metal hydrido complex can be used. Methods for preparing an asymmetric metal complex are described in Angew. Chem., Int. Ed. Engl., 1997, 36, 285-288 and J. Org. Chem., 1999, 64, 2186-2187. Furthermore, the asymmetric metal hydrido complex or asymmetric metal amido complex prepared from the optically active nitrogen-containing compound, the compound of a metal of group VIII of the periodic table, and the base may be reacted with the compound represented by general formula (B) to give an asymmetric metal complex, which is then mixed and reacted as a catalyst with the compounds represented by general formulae (A) and (B) (Reference Example 2).

[0434] The reaction can be carried out in various types of solvent. Examples thereof include an aliphatic hydrocarbon such as pentane, hexane, cyclopentane, or cyclohexane, an aromatic compound such as toluene or xylene, a halogen compound such as dichloromethane, a ketone solvent such as acetone, methyl ethyl ketone, or cyclohexanone, an alcoholic solvent such as methanol, ethanol, 2-propanol, or 2-methyl-2-propanol, and an organic compound such as tetrahydrofuran, diethyl ether, dimethylsulfoxide (DMSO), dimethylformamide(DMF), or acetonitrile, and they may be used singly or in combination.

[0435] In the catalytic reaction, the concentrations of the compounds represented by general formulae (A) and (B) are from 0.01 mol/L of the above-mentioned solvent to a state in which no solvent is used, and preferably in the range of 0.1 to 3.0 mol/L. The amounts of the compounds represented by general formulae (A) and (B) relative to the asymmetric metal complex having the metal atom of group VIII of the periodic table are usually expressed as a molar ratio (S/C) of the reaction substrate relative to the asymmetric metal complex having the metal atom of group VIII of the periodic table, and S/C is in the range of 10 to 100,000, and preferably 50 to 2,000. The reaction temperature is on the order of −20° C. to 100° C. from the viewpoint of cost efficiency. More practically, the reaction can be carried out at around a room temperature of 20° C. to 40° C. The reaction time varies depending on the reaction conditions such as the reaction substrate concentration, the temperature, and the pressure, but the reaction is completed in a few minutes to 100 hours. The product can be purified by a known method such as column chromatography, distillation, or recrystallization.

EXAMPLES

[0436] The present invention is explained further in detail below with reference to Examples, but the present invention is not limited by the Examples. In the Examples, % ee denotes the percentage enantiomeric excess, and S/C denotes the molar ratio of the substrate to the catalyst (molar ratio of the substrate to ruthenium).

[0437] Furthermore, Tsdpen denotes N-(p-toluenesulfonyl)-1,2-diphenylethylenediamine and Msdpen denotes N-methanesulfonyl-1,2-diphenylethylenediamine.

Reference Example 1

[0438] Synthesis of the asymmetric ruthenium amide complex Ru[(S,S)-Tsdpen] (hexamethylbenzene)

[0439] Under an atmosphere of argon, 134 mg (0.2 mmol) of [RuCl₂(hexamethylbenzene)]₂, 147 mg (0.4 mmol) of (S,S)-TSDPEN, 183 mg (2.8 mmol) of potassium hydroxide, 3 mL of methylene chloride, and 3 mL of water were placed in a 20 mL Schlenk tube and stirred at room temperature for 1 hour. The organic phase was washed with water several times, and sodium sulfate was then added to the organic phase to dry it. The organic phase was further dried with CaH₂ and then filtered, the solvent was removed by distillation, and the residue was dried under vacuum. The violet crystals thus obtained were used directly in a reaction as a catalyst.

[0440] By the same procedure as in Reference Example 1, Ru[(S,S)-Tsdpen](1,2,3,4,5-pentamethylbenzene), Ru[(S,S)-Tsdpen](1,2,4,5-tetramethylbenzene), Ru[(S,S)-Tsdpen](1,3,5-trimethylbenzene), Ru[(S,S)-Tsdpen](p-cymene), and Ru[(S,S)-Msdpen](hexamethylbenzene) were synthesized. Furthermore, RuH[(R,R)-Tsdpen](1,3,5-trimethylbenzene) was synthesized by carrying out the reaction of Reference Example 1 in 2-propanol.

Example 1

[0441] Production of (R)-3-[bis(methoxycarbonyl)methyl]cyclohexanone

[0442] Under an atmosphere of argon, 12.6 mg (0.02 mmol, S/C=50) of Ru[(S,S)-Tsdpen] (hexamethylbenzene), 97 μL (1.0 mmol) of 2-cyclohexenone, 114 μL (1.0 mmol) of dimethyl malonate, and 1 mL of 2-methyl-2-propanol were placed in a 20 mL Schlenk tube and stirred at 30° C. for 48 hours. This solution was purified by flash column chromatography (hexane/acetone=90/10, SiO₂) to give 213 mg (93% yield) of the title compound. The optical purity was measured by HPLC (CHIRALPAK AS manufactured by Daicel Chemical Industries, Ltd., hexane: 2-propanol=85:15, flow rate 0.5 mL/min, detection at 210 nm) and it was found to be 96% ee.

Example 2

[0444] Under an atmosphere of argon, 24.0 mg (0.04 mmol, S/C=50) of RuH[(R,R)-Tsdpen] (1,3,5-trimethylbenzene), 194 μL (2.0 mmol) of 2-cyclohexenone, 229 μL (2.0 mmol) of dimethyl malonate, and 2 mL of acetone were placed in a 20 mL Schlenk tube and stirred at 30° C. for 48 hours. This solution was purified by flash column chromatography (hexane/acetone=90/10, SiO₂) to give 316 mg (69% yield) of the title compound. The optical purity was measured by HPLC (CHIRALPAK AS manufactured by Daicel Chemical Industries, Ltd., hexane:2-propanol=85:15, flow rate 0.5 mL/min, detection at 210 nm) and it was found to be 73% ee.

Example 3

[0445] Production of (S)-3-[bis(ethoxycarbonyl)methyl]cyclohexanone

[0446] Under an atmosphere of argon, 24.0 mg (0.04 mmol, S/C=50) of RuH[(R,R)-Tsdpen] (1,3,5-trimethylbenzene), 194 μL (2.0 mmol) of 2-cyclohexenone, 304 μL (2.0 mmol) of diethyl malonate, and 2 mL of acetone were placed in a 20 mL Schlenk tube and stirred at 30° C. for 48 hours. This solution was purified by flash column chromatography (hexane/acetone=90/10, SiO₂) to give 330 mg (64% yield) of the title compound. After this was converted into an ethylene ketal derivative as shown below, the optical purity was measured by HPLC (CHIRALCEL OD manufactured by Daicel Chemical Industries, Ltd., hexane: 2-propanol=97:3, flow rate 0.5 mL/min, detection at 210 nm) and it was found to be 77% ee.
